Some verse chosen for reflection (4)
I believe the answer is:
echo
'reflection' is the definition.
(echo is a kind of reflection)
'some verse chosen for' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'ECHO' is hidden within 'verse chosen for'.
(Other definitions for echo that I've seen before include "call back" , "The distant sound" , "Repetition by reflection" , "Repeating of sound" , "ring" .)
